Regression arise from ISO#fuel-7.0-250-2015-08-28

Scenario:

            1. Create cluster
            2. Add 3 nodes with controller role
            3. Add 2 node with compute role
            4. Setup bonding for all interfaces (including admin interface
               bonding)
            5. Run network verification

Console log:
